Increased risk of metastasis in patients with incidental use of renin-angiotensin system inhibitors: a retrospective analysis for multiple types of cancer based on electronic medical records. Hypertens Res 2022; 45:1869-1881. [PMID: 36171325 DOI: 10.1038/s41440-022-01038-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 08/06/2022] [Accepted: 08/13/2022] [Indexed: 02/03/2023]
Abstract
Renin-angiotensin system inhibitors have been shown to prevent cancer metastasis in experimental models, but there are limited data in clinical studies. We aimed to explore whether renin-angiotensin system inhibitors administered during the period of cancer resection can influence the subsequent development of metastasis by analyzing multiple individual types of primary cancers. A total of 4927 patients who had undergone resection of primary cancers at Kyushu University Hospital from 2009 to 2014 were enrolled and categorized into 3 groups based on the use of antihypertensive drugs: renin-angiotensin system inhibitors, other drugs, and none. Cumulative incidence functions of metastasis, treating death as a competing risk, were calculated, and the difference was examined among groups by Gray's test. Fine and Gray's model was employed to evaluate multivariate-adjusted hazards of incidental metastasis. In the multivariate-adjusted analysis, patients with skin and renal cancers showed statistically higher risks of metastasis with the use of renin-angiotensin system inhibitors (hazard ratio [95% confidence interval], 5.81 [1.07-31.57] and 4.24 [1.71-10.53], respectively). Regarding pancreatic cancer, patients treated with antihypertensive drugs other than renin-angiotensin system inhibitors had a significantly increased risk of metastasis (hazard ratio [95% confidence interval], 3.31 [1.43-7.69]). Future larger studies are needed to ascertain whether renin-angiotensin system inhibitors can increase the risk of metastasis in skin and renal cancers, focusing on specific tissue types and potential factors associated with renin-angiotensin system inhibitor use.

Biomedicines 2022; 10:biomedicines10112988. [PMID: 36428556 PMCID: PMC9687343 DOI: 10.3390/biomedicines10112988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/13/2022] [Accepted: 11/15/2022] [Indexed: 11/24/2022] Open
Abstract
Cancer metastasis and treatment resistance are the main causes of treatment failure and cancer-related deaths. Their underlying mechanisms remain to be fully elucidated and have been attributed to the presence of cancer stem cells (CSCs)-a small population of highly tumorigenic cancer cells with pluripotency and self-renewal properties, at the apex of a cellular hierarchy. CSCs drive metastasis and treatment resistance and are sustained by a dynamic tumor microenvironment (TME). Numerous pathways mediate communication between CSCs and/or the surrounding TME. These include a paracrine renin-angiotensin system and its convergent signaling pathways, the immune system, and other signaling pathways including the Notch, Wnt/β-catenin, and Sonic Hedgehog pathways. Appreciation of the mechanisms underlying metastasis and treatment resistance, and the pathways that regulate CSCs and the TME, is essential for developing a durable treatment for cancer. Pre-clinical and clinical studies exploring single-point modulation of the pathways regulating CSCs and the surrounding TME, have yielded partial and sometimes negative results. This may be explained by the presence of uninhibited alternative signaling pathways. An effective treatment of cancer may require a multi-target strategy with multi-step inhibition of signaling pathways that regulate CSCs and the TME, in lieu of the long-standing pursuit of a 'silver-bullet' single-target approach.

Angiotensin II promotes primary tumor growth and metastasis formation of murine TNBC 4T1 cells through the fibroblasts around cancer cells. Eur J Pharmacol 2021; 909:174415. [PMID: 34375673 DOI: 10.1016/j.ejphar.2021.174415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 08/02/2021] [Accepted: 08/06/2021] [Indexed: 10/20/2022]
Abstract
Angiotensin II (Ang II) reportedly facilitates primary tumor growth and distal hematogenous metastasis formation in various murine intravenous metastasis models. However, it is unclear whether Ang II accelerates the initial processes of metastasis formation that begins in primary tumors surrounded by tumor microenvironment. We examined the effects of Ang II on primary tumors and lung metastasis lesions using a murine spontaneous metastasis model, in which triple negative breast cancer 4T1 cells constitutively expressing luciferase (4T1-Luc cells) were injected into the mammary fat pad of BALB/c mice. Subcutaneous injection of Ang II significantly accelerated primary tumor growth and lung metastasis formation. Ang II increased the protein expression levels of c-Myc, cyclin D1, fibronectin, vimentin, αSMA and Snail, and the treatment with the Ang II type 1 receptor blocker valsartan significantly suppressed the Ang II-induced increases of fibronectin and vimentin. Valsartan also significantly reduced lung metastatic lesions. However, Ang II did not have significant effects on 4T1-Luc cells including the proliferation, migration, invasion, or the expressions of proteins related to cell proliferation and epithelial-to-mesenchymal transition. In contrast, when 4T1-Luc cells were co-cultured with dermal fibroblasts, Ang II significantly accelerated cell migration and increased the expressions of fibronectin, vimentin, αSMA and Snail in 4T1-Luc cells. And moreover, Ang II significantly increased the mRNA expression of IL-6 in fibroblasts co-cultured with 4T1-Luc cells. These results suggested that Ang II accelerates surrounding fibroblasts by soluble factors such as IL-6 to promote epithelial-to-mesenchymal transition, which result in the initiation of cancer metastasis.

The Therapeutic Potential of Targeting the Angiotensin Pathway as a Novel Therapeutic Approach to Ameliorating Post-Surgical Adhesions. Curr Pharm Des 2021; 28:180-186. [PMID: 34176457 DOI: 10.2174/1381612827666210625153011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 04/27/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Post-surgical adhesion is a common complication after abdominal or pelvic surgeries. Despite improvements in surgical techniques or the application of physical barriers, little improvements have been achieved. It causes bowel obstruction, pelvic pain, and infertility in women and has an adverse effect on the quality of life. Renin-Angiotensin System (RAS) is traditionally considered as a blood pressure regulator. However, recent studies also indicate that the RAS plays a vital role in other processes, including oxidative stress, fibrosis, proliferation, inflammation, and the wound healing process. Angiotensin II (Ang II) is the main upstream effector of the RAS that can bind to the AT1 receptor (ATIR). A growing body of evidence has revealed that targeting Angiotensin-Converting Enzyme Inhibitors (ACEIs), Angiotensin II type 1 Receptor Blockers (ARBs), and Direct Renin Inhibitors (DRIs) can prevent post-surgical adhesions. Here we provide an overview of the therapeutic effect of RAS antagonists for adhesion. METHODS PubMed, EMBASE, and the Cochrane library were reviewed to identify potential agents targeting the RAS system as a potential approach for post-surgical adhesion. RESULTS Available evidence suggests the involvement of the RAS signaling pathway in inflammation, proliferation, and fibrosis pathways as well as in post-surgical adhesions. Several FDA-approved drugs are being used for targeting the RAS system. Some of them are being tested in different models to reduce fibrosis and improve adhesion after surgery, including Telmisartan, valsartan, and enalapril. CONCLUSION Identification of the pathological causes of post-surgical adhesion and the potential role of targeting Renin-Angiotensin System may help prevent this problem. Based on the pathological function of RAS signaling after surgeries, the administration of ARBs may be considered as a novel and efficient approach to prevent postsurgical adhesions. Pre-clinical and clinical studies should be carried out to have better information on the clinical significance of this therapy against post-surgical adhesion formation.

Abstract
The association between kidney disease and cancer is multifaceted and complex. Persons with chronic kidney disease (CKD) have an increased incidence of cancer, and both cancer and cancer treatments can cause impaired kidney function. Renal issues in the setting of malignancy can worsen patient outcomes and diminish the adequacy of anticancer treatments. In addition, the oncology treatment landscape is changing rapidly, and data on tolerability of novel therapies in patients with CKD are often lacking. Caring for oncology patients has become more specialized and interdisciplinary, currently requiring collaboration among specialists in nephrology, medical oncology, critical care, clinical pharmacology/pharmacy, and palliative care, in addition to surgeons and urologists. To identify key management issues in nephrology relevant to patients with malignancy, KDIGO (Kidney Disease: Improving Global Outcomes) assembled a global panel of multidisciplinary clinical and scientific expertise for a controversies conference on onco-nephrology in December 2018. This report covers issues related to kidney impairment and solid organ malignancies as well as management and treatment of kidney cancer. Knowledge gaps, areas of controversy, and research priorities are described.

Abstract
Metastasis is a dynamic succession of events involving the dissemination of tumour cells to distant sites within the body, ultimately reducing the survival of patients with cancer. To colonize distant organs and, therefore, systemically disseminate within the organism, cancer cells and associated factors exploit several bodily fluid systems, which provide a natural transportation route. Indeed, the flow mechanics of the blood and lymphatic circulatory systems can be co-opted to improve the efficiency of cancer cell transit from the primary tumour, extravasation and metastatic seeding. Flow rates, vessel size and shear stress can all influence the survival of cancer cells in the circulation and control organotropic seeding patterns. Thus, in addition to using these fluids as a means to travel throughout the body, cancer cells exploit the underlying physical forces within these fluids to successfully seed distant metastases. In this Review, we describe how circulating tumour cells and tumour-associated factors leverage bodily fluids, their underlying forces and imposed stresses during metastasis. As the contribution of bodily fluids and their mechanics raises interesting questions about the biology of the metastatic cascade, an improved understanding of this process might provide a new avenue for targeting cancer cells in transit.

Abstract
Renin-angiotensin system (RAS) inhibitors (RASi)-widely prescribed for the treatment of cardiovascular diseases-have considerable potential in oncology. The RAS plays a crucial role in cancer biology and affects tumor growth and dissemination directly and indirectly by remodeling the tumor microenvironment. We review clinical data on the benefit of RASi in primary and metastatic tumors and propose that, by activating immunostimulatory pathways, these inhibitors can enhance immunotherapy of cancer.

Abstract
Hypertension, which often exists as a comorbid condition in cancer patients, is considered as a factor affecting cancer progression. The renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure, and angiotensin II (Ang II) is a well-known pressor peptide in RAS. There is also accumulated evidence indicating that Ang II plays a critical role in the metastasis of various cancers by modulating adhesion, migration invasion, proliferation, and angiogenesis. Consistent with this, large epidemiological studies have reported the potential beneficial effects of angiotensin-converting enzyme (ACE) inhibitors and Ang II type 1 receptor blockers (ARBs) against cancer metastasis; however, some of the results remain controversial. Although the precise Ang II-related mechanisms involved in cancer metastasis are not completely clear yet, a number of basic and meta-analytic studies have shown that ACE inhibitors and ARBs reduce the metastatic potential of tumors. In this review, we summarize the relationships among hypertension, RAS, and metastasis as demonstrated in basic and clinical studies. Finally, we discuss the possibility of using RAS inhibitors as anti-metastatic drugs.

Abstract
To assess the current evidence on the potential benefit of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) on cancer recurrence and survival, we comprehensively searched PubMed, Embase, and the Cochrane Library from their inception to April 2013. Two authors screened out duplicates and independently reviewed the eligibility of each study. We included comparative studies comparing the use and nonuse of ACEIs or ARBs in cancer patients. Primary outcomes were disease-free survival (DFS) and overall survival. We included 11 studies with 4964 participants in the final analysis. The meta-analysis showed that the use of ACEIs or ARBs resulted in a significant improvement in DFS [hazard ratio (HR) 0.60; 95% confidence interval (CI) 0.41-0.87; P=0.007)] and overall survival (HR 0.75; 95% CI 0.57-0.99; P=0.04). Even when cancer stage was classified into low (I/II) or high (III/IV), DFS improvement was applied to both low stage (HR 0.56; 95% CI 0.32-0.96; P=0.04) and high stage (HR 0.59; 95% CI 0.37-0.94; P=0.03). Analysis according to cancer type showed benefits in urinary tract cancer (HR 0.22), colorectal cancer (HR 0.22), pancreatic cancer (HR 0.58), and prostate cancer (HR 0.14), but not in breast cancer and hepatocellular cancer. This meta-analysis provides evidence that the use of ACEIs or ARBs in cancer patients can lead to a 40 and 25% reduction in the risk of cancer recurrence and mortality.

Abstract
BACKGROUND The relation of dialysis to tumor recurrence in patients with upper tract urothelial cancer (UTUC) is unknown; however, a limited number of small-scale studies suggest that patients with renal diseases prior to UTUC are more likely to exhibit bladder recurrence. We performed a population-based analysis to determine the effect of dialysis on bladder recurrence for patients with UTUC. METHODS This retrospective cohort study included patients diagnosed with UTUC (2002-2007) from the Taiwan National Cancer Registry and divided them into two groups-dialysis and non-dialysis groups. These patients were followed up until bladder recurrence, death, or the end of 2010. Competing risk analyses adjusting covariates and death were applied to determine the relation of dialysis and bladder recurrence. RESULTS Of the 5141 eligible patients, 548 (10.7%) were undergoing dialysis. The cumulative bladder recurrence was significantly higher in the dialysis group than in the non-dialysis group (29% vs. 21%, modified log-rank p < 0.001). In the multivariable analysis, the dialysis group exhibited a 64% increased bladder recurrence risk (cause-specific hazard ratio 1.64, 95% confidence interval 1.34-2.01, p < 0.001), which was confirmed using stratification and propensity score weighting methods. The other prognostic factors for bladder recurrence were sex, diabetes, cardiac disorder, Charlson Comorbidity Index, and tumor grade. CONCLUSIONS Despite unknown reasons, approximately one-tenth of patients with UTUC have experienced dialysis treatment. Patients undergoing dialysis have a higher risk of bladder recurrence. Various treatment and screening strategies should be developed for dialysis and non-dialysis patients.

Evaluation of the Clinical Utility of Renin-Angiotensin System Inhibitors in Patients Undergoing Radical Surgery for Urothelial Carcinoma of the Upper Urinary Tract. Clin Genitourin Cancer 2017; 15:e943-e954. [PMID: 28552573 DOI: 10.1016/j.clgc.2017.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2017] [Revised: 04/25/2017] [Accepted: 05/01/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Renin-angiotensin system (RAS) inhibitors are effective for treating patients with cancer. The present study evaluated the impact of RAS inhibitors, including angiotensin-2 converting enzyme inhibitors and angiotensin 2 receptor blockers, after patients underwent radical surgery for upper urinary tract urothelial carcinoma (UTUC). METHODS This retrospective study included 312 patients with nonmetastatic UTUC who underwent radical surgery. The oncological outcomes of patients treated or not treated with RAS inhibitors following surgery were evaluated. Recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were assessed using the Kaplan-Meier method and Cox regression analysis. RESULTS The median follow-up duration after radical surgery was 44.7 months. The 5-year RFS, CSS, and OS rates of patients who did or did not receive RAS inhibitors were 82.3% versus 68.9% (P = .018), 88.9% versus 71.8% (P = .0044), and 68.7% versus 61.8% (P = .047), respectively. Multivariable analyses revealed that the use of RAS inhibitors was an independent prognostic factor for RFS, CSS, and OS (hazard ratio [HR] 0.48, P = .013; HR 0.31, P = .002; and HR 0.52, P = .01, respectively). Moreover, patients treated with RAS inhibitors versus untreated patients had better 5-year RFS compared with those in the pT2 and < pN1 subgroups (pT2: 100.0% vs. 62.2%, P = .014 and < pN1: 87.2% vs. 74.7%, P = .034). CONCLUSIONS RAS inhibitors significantly improved RFS, CSS, and OS of patients with UTUC who underwent radical surgery. These agents may be particularly beneficial for patients with stage pT2 or < pN1 disease.

Abstract
BACKGROUND Renin-angiotensin system inhibitors (RAS inhibitors) are antihypertensive agents with potential antitumor effects. However, various studies have yielded conflicting results on the influence of RAS inhibitors on survival of cancer patients. The aim of this study was to evaluate the effect of RAS inhibitors on recurrence, metastasis, and survival in cancer patients through a meta-analysis. METHODS PubMed, Web of Science, EMBASE, and Cochrane Library were systematically searched from inception to December 2016. The pooled hazard ratio (HR) with its 95% confidence interval (95% CI) was calculated to evaluate the association between RAS inhibitors and recurrence, metastasis, and survival in cancer patients. RESULTS Fifty-five eligible studies were included in the present meta-analysis. Results showed that there were significant improvements in overall survival (OS) (HR = 0.82; 95% CI: 0.77-0.88; P < 0.001), progression-free survival (HR = 0.74; 95% CI: 0.66-0.84; P < 0.001), and disease-free survival (HR = 0.80; 95% CI: 0.67-0.95; P = 0.01) in RAS inhibitor users compared with nonusers. Subgroup analyses revealed that the effect of RAS inhibitors on OS depended on the cancer type or different RAS inhibitors. CONCLUSION This meta-analysis suggests that RAS inhibitors could improve the survival of cancer patients and depend on cancer type and types of RAS inhibitors.

Abstract
PURPOSE Prior reports suggest that renin-angiotensin system inhibition may decrease nonmuscle invasive bladder cancer recurrence. We evaluated whether angiotensin converting enzyme inhibitor or angiotensin receptor blocker treatment at initial surgery was associated with decreased recurrence or progression in patients with nonmuscle invasive bladder cancer. MATERIALS AND METHODS Using an institutional bladder cancer database we identified 340 patients with data available on initial transurethral resection of bladder tumor. Progression was defined as an increase to stage T2. Cox proportional hazards models were used to evaluate associations with recurrence-free and progression-free survival. RESULTS Median patient age was 69.6 years. During a median followup of 3 years (IQR 1.3-6.1) 200 patients (59%) had recurrence and 14 (4.1%) had stage progression. Of those patients 143 were receiving angiotensin converting enzyme inhibitor/angiotensin receptor blockers at the time of the first transurethral resection. On univariate analysis factors associated with improved recurrence-free survival included carcinoma in situ (p = 0.040), bacillus Calmette-Guérin therapy (p = 0.003) and angiotensin converting enzyme inhibitor/angiotensin receptor blocker therapy (p = 0.009). Multivariate analysis demonstrated that patients treated with bacillus Calmette-Guérin therapy (HR 0.68, 95% CI 0.47-0.87, p = 0.002) or angiotensin converting enzyme inhibitor/angiotensin receptor blocker therapy (HR 0.61, 95% CI 0.45-0.84, p = 0.005) were less likely to experience tumor recurrence. The 5-year recurrence-free survival rate was 45.6% for patients treated with angiotensin converting enzyme inhibitor/angiotensin receptor blockers and 28.1% in those not treated with angiotensin converting enzyme inhibitor/angiotensin receptor blockers (p = 0.009). Subgroup analysis was performed to evaluate nonmuscle invasive bladder cancer pathology (Ta, T1 and carcinoma in situ) in 85 patients on bacillus Calmette-Guérin therapy alone and in 52 in whom it was combined with angiotensin converting enzyme inhibitor/angiotensin receptor blocker. Multivariate analysis revealed that patients treated with bacillus Calmette-Guérin alone (HR 2.19, 95% CI 1.01-4.77, p = 0.04) showed worse recurrence-free survival compared to patients treated with bacillus Calmette-Guérin and angiotensin converting enzyme inhibitor/angiotensin receptor blocker (stage Ta HR 0.45, 95% CI 0.21-0.98, p = 0.04). CONCLUSIONS Pharmacological inhibition of the renin-angiotensin system is associated with improved outcomes in patients with bladder cancer. Renin-angiotensin system inhibitor administration in nonmuscle invasive bladder cancer cases should be studied in a prospective randomized trial.

Abstract
Angiotensin II is a key biological peptide in the renin-angiotensin system that regulates blood pressure and renal hemodynamics, and extensive experimental studies have shown that angiotensin II promotes diverse fibrotic changes and induces neovascularization in several inflammatory diseases. It is known that angiotensin II can be controlled using renin-angiotensin system blockade when angiotensin II is the main factor inducing a particular disease, and renin-angiotensin system blockade has assumed a central role in the treatment of inflammatory nephritis, cardiovascular disorders and retinopathy. In contrast, renin-angiotensin system blockade was found to have not only these effects but also other functions, such as inhibition of cancer growth, angiogenesis and metastasis. Numerous studies have sought to elucidate the mechanisms and support these antitumor effects. However, a recent meta-analysis showed that renin-angiotensin system blockade use might in fact increase the incidence of cancer, so renin-angiotensin system blockade use has become somewhat controversial. Although the renin-angiotensin system has most certainly made great contributions to experimental models and clinical practice, some issues still need to be resolved. The present review discusses the contribution and controversy surrounding the renin-angiotensin system up to the present time.

Abstract
BACKGROUND Angiotensin 2 is a key biologic peptide in the renin-angiotensin system (RAS) that regulates blood pressure and renal hemodynamics. The potential role of the RAS in the promotion of tumor growth, angiogenesis, and metastasis also has been shown in the past few decades. This study investigated the prognostic impact of RAS blockade on patients with renal cell carcinoma (RCC) after surgery. METHODS The study identified 557 patients with pathologically diagnosed RCC (pT1-4 N0M0) and evaluated the prognostic factors after surgery for patients administered or not administered angiotensin-converting enzyme inhibitors (ACEs) or angiotensin 2 receptor blockers (ARBs). RESULTS The median follow-up period was 5.1 years. Radical nephrectomy was performed for 349 patients (62.7 %), whereas the remaining 208 patients (37.3 %) underwent partial nephrectomy. A total of 104 patients (18.7 %) were administered RAS inhibitors: ACEs (n = 22) or ARBs (n = 82). Multivariate analysis showed that administration of RAS inhibitors (P = 0.044; HR 2.69), longer tumor length (P < 0.001; HR 1.02), high-grade tumor (P < 0.001; HR 3.55), and positive microvascular invasion (P < 0.003; HR 3.13) were not independent risk factors for a decrease in subsequent disease-specific survival after surgery for RCC. The 5-year disease-specific survival rate was 96.8 % among the patients administered RAS inhibitors and 89.8 % among their counterparts (P = 0.019). CONCLUSIONS The authors propose renin-angiotensin blockade as a possible potent choice for effective treatment after surgical treatment of RCC.

Abstract
INTRODUCTION The aim of this study is to evaluate whether the administration of renin-angiotensin system (RAS) inhibitors, angiotensin-I converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs), is associated with treatment outcome in patients with esophageal squamous cell carcinoma. MATERIALS AND METHODS A total of 141 esophageal squamous cell carcinoma patients receiving esophagectomy were identified, and were divided into two groups: an ACEI/ARB group (n=20), and a non-ACEI/ARB group (n=121). The effect of ACEIs or ARBs on cell proliferation and vascular endothelial growth factor (VEGF) secretion of esophageal squamous cell carcinoma cell lines, CE81T/VGH and TE2, were investigated by 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and Enzyme-linked immunosorbent assay (ELISA), respectively. RESULTS Use of ACEI/ARB (p=0.032), pathologic T stage (p<0.001), pathologic N stage (p=0.012), tumor stage (p=0.006), and tumor location (p=0.032) were significantly associated with superior overall survival. In multivariate comparison, use of ACEI/ARB (p=0.006), tumor stage (p=0.002), and tumor location (p=0.014) represented the independent prognosticators of superior overall survival. In cell lines, ACEIs/ARBs inhibit cell proliferation and VEGF secretion in a dose-dependent manner. CONCLUSIONS ACEIs/ARBs administration is independently associated with superior overall survival in patients with esophageal squamous cell carcinoma receiving esophagectomy. Our data support further investigation of the role of RAS inhibitors as a potential therapy in esophageal squamous cell carcinoma.

Transcriptome-based analysis of kidney gene expression changes associated with diabetes in OVE26 mice, in the presence and absence of losartan treatment. PLoS One 2014; 9:e96987.

Abstract
Diabetes is among the most common causes of end-stage renal disease, although its pathophysiology is incompletely understood. We performed next-generation sequencing-based transcriptome analysis of renal gene expression changes in the OVE26 murine model of diabetes (age 15 weeks), relative to non-diabetic control, in the presence and absence of short-term (seven-day) treatment with the angiotensin receptor blocker, losartan (n = 3-6 biological replicates per condition). We detected 1438 statistically significant changes in gene expression across conditions. Of the 638 genes dysregulated in diabetes relative to the non-diabetic state, >70% were downregulation events. Unbiased functional annotation of genes up- and down-regulated by diabetes strongly associated (p<1 × 10(-8)) with terms for oxidative stress and for endoplasmic reticulum stress/protein folding. Most of the individual gene products up- or down-regulated with diabetes were unaffected by losartan treatment; however, of the gene products dysregulated in diabetes and influenced by losartan treatment, the vast majority of changes were in the direction of amelioration rather than exacerbation of the diabetic dysregulation. This group of losartan-protected genes associated strongly with annotation terms for endoplasmic reticulum stress, heat shock proteins, and chaperone function, but not oxidative stress; therefore, the losartan-unaffected genes suggest avenues for additional therapeutic opportunity in diabetes. Interestingly, the gene product most highly upregulated by diabetes (>52-fold), encoded by the cationic amino acid transporter Slc7a12, and the gene product most highly downregulated by diabetes (>99%)--encoded by the "pseudogene" Gm6300--are adjacent in the murine genome, are members of the SLC7 gene family, and are likely paralogous. Therefore, diabetes activates a near-total genetic switch between these two paralogs. Other individual-level changes in gene expression are potentially relevant to diabetic pathophysiology, and novel pathways are suggested. Genes unaffected by diabetes alone but exhibiting increased renal expression with losartan produced a signature consistent with malignant potential.

Abstract
There are conflicting reports on cancer risk associated with angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs). This retrospective cohort study was conducted to analyze the risk of cancer development in patients who received ACE inhibitors/ARBs as treatment for essential hypertension. Using the Taiwan National Health Insurance Research Database, 297,688 eligible study patients with essential hypertension were identified. According to their antihypertensive prescriptions, the study patients were stratified into an ACE inhibitor group, an ARB group, or a control group. After matching, participants were observed for the occurrence of cancer. In the ACE inhibitor group compared with the control group, the hazard ratio was 0.51 (95% confidence interval, 0.39-0.68). In the ARB group compared with the control group, the hazard ratio was 0.8 (95% confidence interval, 0.65-0.97). Regular use of ACE inhibitors/ARBs was not associated with an increased risk of cancer development and was actually found to decrease overall cancer risk in this study.
